Mine is down low just forward of the tandem axles. I don't have to get under the trailer since the cover is reachable at the edge of the trailer. Quite honestly if I can't bend down to open that tube, I'd not be able to hook the hose up to the drain, hook up the fresh water to the city inlet, pull out the electrical cord, hook up the satellite cable, and finally access the stabilizer jacks. So the day I can't bend down to these is the day you will see this trailer on the classifieds!
